Female teacher Anna Komukai is forced to undergo a medical examination by the school nurse in the infirmary. However, the doctor, captivated by her big tits, uses the examination as an excuse to engage in lewd conversation and deliberately performs sexual acts. In response, Anna resists, but is raped and photographed as a means of silencing her. The next day, the photos are shown to her students in the classroom, and Anna is threatened into becoming the sexual target of the students' desires. A brutal stripping session, handjobs, rimjobs, and 20 consecutive creampie sex scenes follow.
